Properties

Chromium Oxide Green is a dull, dense, willow or pale green colour that is entirely opaque. It has an average drying time and a low tinting strength. It is relatively flexible in oil form and is suitable for all purposes and mediums.

This pigment is less versatile in mixtures than Viridian and Phthalocyanine Green but mixes well with other colours without overpowering them.

Permanence

Chromium Oxide Green has excellent permanence, even at high temperatures.

Toxicity

Chromium Oxide Green is slightly toxic. Evidence of Chromium(III) carcinogenicity is inconclusive. Chromium(III) salts appear in greenish pigments such as PG17. Chromium(VI) salts, which appear in yellowish pigments, have been proven to cause cancer.

History

Louis-Nicolas Vauquelin discovered the element chromium in lead chromate in 1797. It began to be used as an enamel and ceramic colour in 1809, but it had limited use as a pigment until 1862 because of its cost.

It is the most commonly used green for military camouflage because it appears the same shade as living foliage under infrared light.
